Method

Heat olive oil in a pan and sauté onion for 3 minutes. Add red pepper, salt and pepper; sauté another minutes or until vegetables are soft. Remove mixture from heat and place in bowl. Add a little more olive oil to the pan and lightly fry zucchini slices until soft (2-3 minutes). To assemble sandwich, spread mayonnaise on top slice of rye bread and Dijon mustard on bottom slice.
